Lowers the barrier for sister sites to build their own plugins. Generated output satisfies the framework contract out of the box. CLI command (shopdb/plugins/cli.py): - `flask plugin new <name> --description "..."` generates a plugin skeleton under plugins/<name>/. Validates the name against CONTRIBUTING.md rules (lowercase letters/digits only, no underscores or hyphens, not in the reserved list) and refuses to overwrite existing plugins unless --overwrite is passed. - Output prints the next steps (install, migrate, test). Scaffolder (shopdb/plugins/scaffolder.py): - validate_name: enforces the naming rules - pascal_case: lowercase-to-PascalCase for class names - scaffold_plugin: copies templates with string.Template substitution. Three placeholders: $name, $Name, $description. Files with `model.py` in the path get renamed to <name>.py. Templates (shopdb/plugins/templates/): - manifest.json.tmpl: name, version 0.1.0, description, core_version range >=0.1.0,<1.0.0 (broad enough to survive minor framework bumps) - plugin.py.tmpl: <Name>Plugin class extending BasePlugin with all required hooks implemented (meta from manifest, get_blueprint returning the bp, get_models returning the example model). Includes on_install hook that seeds the AssetType row. - models/__init__.py.tmpl + models/model.py.tmpl: Asset extension table keyed by assetid with one example field. TODO comment marks it as a placeholder. - api/__init__.py.tmpl + api/routes.py.tmpl: Blueprint with list and detail endpoints using the framework's pagination + response helpers. - schemas/__init__.py.tmpl: marshmallow schema stub. - tests/__init__.py.tmpl + tests/test_plugin.py.tmpl: smoke tests asserting plugin loads, get_blueprint returns Blueprint, get_models returns at least one model. - README.md.tmpl: one-pager for plugin authors with common edits and next-step references. Canary tests (tests/test_plugin_scaffold.py): - 14 tests asserting the scaffold output passes contract checks. - Validates name rules (lowercase, reserved, hyphens, digits, etc.) - Verifies all expected files generated, manifest fields present. - Loads the generated plugin via PluginLoader (spec_from_file_location bypasses the real `plugins` package shadowing). - Asserts subclasses BasePlugin, get_blueprint returns Blueprint, get_models returns model with __tablename__. - Module-scoped fixture; cleans up sys.modules + SQLAlchemy metadata on teardown to avoid cross-test contamination. Quickstart docs (docs/PLUGIN-QUICKSTART.md): - 30-minute walkthrough: scaffold -> edit model -> add routes -> install -> verify -> add hooks. Cross-links to PLUGIN-HOOKS.md and the ADRs. Includes common-errors table. Test count: 87 -> 101 passing. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
# $Name plugin
$description
This plugin was generated by `flask plugin new $name`. It satisfies the framework contract out of the box. Replace the example model and routes with your domain.
## What's here
- `plugin.py` - the `${Name}Plugin` class extending `BasePlugin`. Edit `init_app` for custom setup, `on_install` to seed reference data.
- `models/$name.py` - example Asset extension table. Replace `examplefield` with your domain fields.
- `api/routes.py` - example list and detail endpoints. Add CRUD as needed.
- `schemas/__init__.py` - marshmallow schema stub for request/response validation.
- `tests/test_plugin.py` - smoke tests asserting contract compliance.
- `manifest.json` - plugin metadata. Bump `version` on changes; keep `core_version` range broad.
## Common edits
| You want to... | Do this |
|---|---|
| Add a hook (search, navigation, dashboard widget) | Override the method in `${Name}Plugin`. See `docs/PLUGIN-HOOKS.md`. |
| Accept external collector data | Override `get_collector_schema()` to return a JSON Schema. See ADR-006. |
| Add another model | Create `models/<other>.py`, export it in `models/__init__.py`, return it in `get_models()`. |
| Add a CLI command | Override `get_cli_commands()` returning a list of Click commands. |
## Frontend
Vue components for this plugin live under `frontend/src/views/$name/` (per project convention). Backend scaffolding does not generate frontend yet; copy from an existing plugin's view files (e.g., `frontend/src/views/network/`) as a starting point.
## Install and run
```bash
flask plugin install $name
flask db migrate -m "Add $name plugin tables"
flask db upgrade
pytest plugins/$name/tests/
```
